Limit number of sub categories to display

Hi,

I am using below code to display Subcategory of a active Category. Is there any way to limit the number of subcategory to display and place More link for rest of the subcategories?

<?php
	if (is_category()) {
		$this_category = get_category($cat);
		if (get_category_children($this_category->cat_ID) != "") {
			echo "<ul>";
			wp_list_categories('orderby=id&show_count=0&title_li=
			&use_desc_for_title=1&child_of='.$this_category->cat_ID);
			echo "</ul>";
		}
	}
?>

Thanks ??
